Max Kellermann cbd952b2c4 ceph: fix memory leaks in __ceph_sync_read() 
commit d6fd6f8280 upstream.

In two `break` statements, the call to ceph_release_page_vector() was
missing, leaking the allocation from ceph_alloc_page_vector().

Instead of adding the missing ceph_release_page_vector() calls, the
Ceph maintainers preferred to transfer page ownership to the
`ceph_osd_request` by passing `own_pages=true` to
osd_req_op_extent_osd_data_pages().  This requires postponing the
ceph_osdc_put_request() call until after the block that accesses the
`pages`.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
